I'm running LinuxMint14 on a Toshibat Satellite laptop. Yesterday I was using Banshee to sync playlists to a portable music player, when the laptop shut off without warning by itself. After powering it back on I found I can no longer run Banshee as a normal user. Whenever I try, I get a dialogue box titled "Encountered a Fatal Error: Exception has been thrown by the target of an invocation" with the following details:

Running Banshee with sudo privledges works fine, so I'm guessing it's something in my personal user settings. I've tried starting Banshee with my media player connected but no luck. I've also tried uninstalling and resintalling with no luck. Obviously I can go to RythymBox or something like that but I'd prefer not to have to rebuild all my playlists from scratch, as I have a pretty extensive digital music collection on my laptop. Any suggestions?
